To all whom it 'muy concern:

Be it known that I, FRED E. GILBERT, n citizen of the United States, residing at Jacksonville, in the county. of Duval and State of Florida, ha-ve'invented certain new and useful 'Improvements in Automatic ITunnels; and vI do, hereby declare thefol- Alowing 'to be a full, clear, and exact desci tion Aoi" the invention, such as will ,enebe others skilled in the art to which it upper-- Atains to make and use the same.

This inventionfrelates to an improved automatic funnel and more particularly to that class of unnels in which the flow of the liquid issuing therefrom' isv automatically cut off through the liquid rising to' a predetermined level in the receptacle tobe illed.

The object of this invention is tov provide an automatic funnel which is 4simple and durable in construction, arranged and con, structied to retain the 'liquid in Vthe bowl of the funnel .after the liquid has been prevenir ed from issuin from the nozzle of the funnel und one w ich will be cheap to manu! fac-ture. Y

`To thisend the invention consists of certain novel details of construction and combinntions of parts as will be more fully' pointed out in the Similar reference charnctersindicete like parts throughout the several views.

1 indicates 'the bowl shaped body of the funnel preferably constructed of metal and is bent inwardly and downwardly at its u ing. centrally and vertice y 'of the bowl 1 is a hollow tube 3 closed at one end by e hollow cap 4, perforated at 5 to allow the liquid to pass freely from the bowl l intothe tube 3 and is also perforated at 6 to allow the liquid to escape into any suitable receptacle being filled` The lower end of the tube 3 constitutes the nozzle of the funnel.

A rod 7 which is slidably mounted within the tube 3 carries on its upper end an indicating ball 8, und on its lower end a ilont 9,

slipping. peredge'to form a splash uard2. Exten -und near the upper e(part -of the rod 7 two wln 10 are mount leasing two retaining do 4. TheA wings 10 extend outwardly 'an downwardly, are slotted as at 11 and 12 for receiving Ithe pinsl and 16 carried-ley the vretaining dogs 13 and 14 and are adapt-V Ved to throw. the said d out of e ment with the valve mec ani'sm as .w l hereinafter explained. l'

for engaging and 1e' 13 and 14. "These" dogs' are pivot-elly h ung rom the hollow ,ca'

Ence-cling the rod 7, and Slidabiymcnt-'f ed thereon, 1s a valve stem 17 carrying Ythe ball valves 18 e'nd 19, the latter bein .somewhat ama-ller in diameter-than the orme'r'.

The 'stem v17 also carries on the end'opposite the valve 18 a. cone shaped head 20'which is` adapted to be engaged and held `by thev retanning dogs 13 and 14 while the vulve stem" is in its raised osition.- A

Located within the tube' 3 are -valve seats 21, 22and 23, the seats 21 and 23- being adapted to seat vulves 18 and 19 when theA liquid supply to the no zzle hasbeen cut off a'nd the seat 22 beingfadepted to seat, the valve 18 ywhile the receptac e is being filled. It will thus be seen that while the' valve 18 is in the position shown in Fig. 1 (filling position) no liquid cen be forced out through the top' of 'the tube 3, but will have a free passage through the ports 5 and 6 into thev receptacle to be filled. A string or wire 24 for resetting the valve 18, is attached to the upper end of the valve stem 17 and passes out through the cap 4 and is provided atits outer end with armg 30.

`To facilitetelling the receptacle .lto'any predetermined level a split rin 25 1s pro- .vided forming a stop and is a epted to be moved along the outside of the funnel nozisle. A bolt 26 and 'nut 27 holds the ring frictionally against the nozzle to prevent Fig. 2 is shown the pipe connection for feeding a. liquid to the tube and nozzle under pressure and comprises a pi e T having en annular recess 28 positione vdirectly over the ports 5 in the tube.4 A pipe 294 is connected to the pipe T being also positioned over the ports and liquid entering therethrough under pressure will trave around the annular rece 28 and enter the ports '5 without leakage to the atmosphere.' Theunnel being ready for use and the ring 25 positioned on the nozzle, the same is inserted into the filling openin of the bottle` tank or other receptacle an operates as follows The liquid is poured into the bowl 1, passes through the ports 5, down through the ports 6 and into the receptacle.

lVhen'the receptacle becomes nearly full the.

and allows the 'valves 18 and 19 to drop into the valve seats 21 und 23, the valve 18 preventing the liquid from entering the funnel nozzle and the valve 19 preventing the liquid from entering'the upper part of the tube 3. Thefunnel is now removed from the receptacle and the tra ped liquid is released. To reset the mec anism the string or wire 24 is ulled, thereby' raising the valve stem untiilthe dogs 13 and 14 engage under the cone head 20 when the valve 18 will have left its seat 23 and entered the valve seat 22, thus preventing the liquid from forcin up into the tube 3. The upper portion of t e tube 3 completely ineloses the valve mechanism, as shown in Fig. 1, so as to prevent heavy liquids such as machine oil, molasses, Syrups, ctc., from contacting the said valve mechanism and interfering with its successful operation. It. will be -obvious, therefore, that when the valves are in' the raised position liquid can pass freely through the nozzle 3 (beiner prevented by the valve 1S from entering the upper tube?, but is prevented from passing to the nozz e or to the upper tube portion by the liquidV in the bowl bearing on the valve 18, which tends to seat the valve 19 more firmly, when the sup ly is cut ofi' from the nozzle auto mutical y. i v

It Vis evident that those skilled in the art may vary the details of construction and arrangement ot' parts without de )arting from the spirit of t e invention, an( therefore I do not wish t0 be limited to such features except as may be required bv .die claims.

What; I claim is:

1. An automatic funnel comprising a bowl, u tube providing a nozzle, valves preventing liquid having access to the upper part of said tube, one of said valves pre venting liquid having access to said nozzle, and valve actuating means, substantially as described.

In an automatic funnel, the combinat-ion of a tube constituting a nozzle and pro vided with a plurality of ports, -a iioat, in `said tube, a valve in said tube adapted to control said ports, a valve seat carried by said tube located below said valve, a second valve seat in said tube above said valve, and a connection between said loat and said valve, substantially as described.

3. In an automatic funnel, the combination of .a tube constituting a nozzle and provided with a plurality ot' ports, a loat in said tube, a valve in said tube adapted to control said ports, a valve seat carried by said tube located below said valve, a second valve Seatin said tube above said valve, a connection between said float and said valve, a third valve seat in said tube above Said Second seat, and a valve conc-ting withx said third seat, said valves when 'seated adapted to prevent liquid from flowing either up or down, substantially as described.

4. In an automatic funnel, the combination of a tube constituting a nozzle and prnvided with a plurality of ports, a lioat in said tube, a valve in said tube adapted to control said ports, a valve seat carried by Said tube located below said valve. a second valve seat in said tube above said valve. a third valve seatin said tube above :said sei-- und scat, a second valve enacting willi said third seat, a tube carrying said second valve and provided with a head, a catch adapted t0-contact with said head, an inclined wingl enacting with said cati-h, and connectionsbetween said wing and said lloat, substantially as described.

In testimony whereof, l atlix my signature, in presence of two witnesses.
